Exclamation Brake Light Stuck On

Bought the truck this way. The previous owner said he was bleeding the brakes after installing new rear calipers and let the reservoir get too low and it kicked the Brake light on in the dash. I've checked the two sensors on the master cylinder reservoir with light still on. Fuses are all good. Does the computer save this as like a trouble code and do I have to have a scan tool to erase the light? If this is true let me know. Thanks. -Kevin

I would bleed the front brakes and see if that fixes it.
I think the system looks for low pressure and if it sees it you get the light.
Since the res went low he could have drawn air in the front lines.

Is this the ABS light or actual brake light? Is your speedo doing anything odd? Our trucks love to eat up rear speed sensors.

I did let the front ones gravity bleed and got only fluid, no bubbles. ABS goes off right away when started, but the red brake light stays on no matter what. It doesn't even get brighter or dimmer when I apply the p brake. I was just wondering if throwing a scan tool on it would be able to see what's keeping it on.
